Pitch classifications provided by the Gameday Algorithm and are unfortunately often inaccurate.
Clicking individual pitch types will provide individual velocity histograms for each pitch.

Nibbleness is the arithmetic mean of the distance of each pitch, in inches, from the edge of a normalized strikezone. Lower indicates “more Nibbley”.
Time to Plate is the time, in seconds, that it takes an average pitch of this type to reach the plate. This is strongly correlated with velocity, but also factors in movement.

“There’s a little bit of inflammation still that is contributing to the problem, but structurally he has been checked out as you can imagine, in every way shape or form. Until the soreness gets out of it, it’s a bone bruise. And bone bruises sometimes take time. But as long as we’re in this thing, he’s gonna try to keep going out there and get loosened up and get ready, and we’re going to allow it to happen, so any talk about shutting him down, from anybody other than me, is premature.”

Ozzie Guillen on Jake Peavy:

“I think it would be tough for [us] to see him any time soon because he can’t still throw because of the bruising on his arm. After [he starts throwing] we gotta come out with a plan to make him throw on the side, and the side day and you have to have a simulated game, [after] simulated game you gotta to go wait for a few days to recover, then throw another day, then maybe pitch in the game. I said last week, I believe I don’t [think] we’ll have him the rest of the year because I got to with my realistic plan, I gotta set the rotation [with] what I have now. If he come back, then we make some moves, but right now I [don’t] feel like he’s gonna be here soon, because we gotta go through so many different things and I don’t think we have enough time for that.”

“It’s too early to go down that road. We most assuredly will need a left-handed bat. Whether or not there’s a match … I’m not so sure that’s the best course of action for us to have a pure DH rather than keep it a rotating DH to give guys a break.”

Thome’s actual age is 39. Williams admitted that the two talked about the possibility of Thome coming back to Chicago as a 40-year-old DH in 2010. “It’s too early go down that road,” Williams said. “We most assuredly will need a left-handed bat.”

Jeff (England): Joe Serafin has made a great start to his pro career, especially for a 37th rounder, with a 4.14 K/BB, 1.67 BB/9 as well as an improving K/9 since his jump to Low-A, but is he is for real? And do you know much about what he throws?

Matthew Eddy: White Sox lefty Joey Serafin works in the mid-80s with a fringy breaking ball, but the University of Vermont product shows poise and command, which often can be enough to dominate in Rookie ball and low Class A.

and from a question on Appalachian League prospects:

The White Sox have an 18-year-old Venezuelan catcher named Miguel Gonzalez with Bristol. He’s got a bit of a thick body but he impressed observers by hitting .300 and by driving the ball consistently (15 doubles). If he can stay at catcher, he’s got a shot.

Triple-A Charlotte RHP Carlos Torres (White Sox) didn’t exactly have an easy route to the big leagues, but once the 27-year-old got there, he made the most of the opportunity. After turning in five scoreless innings for the Knights last Friday, Torres earned another callup to the show. Pitching in an interleague make-up game against the Cubs, Torres pitched seven scoreless innings, allowing five hits while striking out six. The righty sits in the low 90s, throws a sharp, mid-80s cutter and mixes in a 76-78 mph curveball

A quick look at Jenks’ line would lead one to believe that he has been much worse in 2009 than in 2008. After all, his ERA is over a full tick higher (2.63 in ‘08, 3.66 in ‘09). However, Bobby’s K/BB ratio has spiked from 2.24 to 3.38. He’s throwing harder (95 MPH in ‘09, 93.8 in ‘08), and opposing hitters aren’t making as much contact against his stuff (78.4% contact rate in ‘09, 84.5% in ‘08). Jenks’ XFIP is 3.66, which is actually lower than his ‘08 mark (3.86). The root cause of his ‘09 struggles is a ballooning HR/FB rate (15.6%). Bobby’s career HR/FB rate is 9.1, and the average for a pitcher tends to hover around 11-12%. Jenks could be a bargain on draft day next year. He’s still the same guy.

Escobar showed no signs of life until suddenly something seems to have clicked. On the season the 20 year-old Venezuelan is still only hitting .262, but he is a great defensive shortstop so his glove will probably be what carries him through the system. …

There’s only one offseason target on [Kenny] Williams’ radar. The money off the books in losing Jim Thome, Jose Contreras, Octavio Dotel as well as possibly Jermaine Dye and Jenks not only covers the losses in ’09 and the additions of Peavy and Rios, but allows Williams one big-ticket item. In this case, a speedy-ticket item.

Chone Figgins, come on down!

The Sox have been infatuated with the speedy leadoff hitter for four years, and now that he becomes a free agent, they’ll make a serious play for him. If the asking price on Figgins is too high, then Scott Podsednik becomes Plan B, as well as talking to Dye about redoing a short-term contract and becoming a designated hitter.
